What does this do that VLC can’t do ?

Any good source for the channels?

$3.99? Yowza

There’s an AUR open-tv package for Arch/Artix/…, and there’s even an AUR open-tv-bin version, but I prefer looking at the build recipes if available, and if not using Arch/Artix/… one can read through the PKGBUILD and see how it builds.
